Auxiliary device for manufacturing main bearing oil feeding pipe of marine diesel machine and main bearing oil feeding pipe manufacturing method

Abstract

The invention relates to an auxiliary device for manufacturing a main bearing oil feeding pipe of a marine diesel engine and a method for manufacturing the main bearing oil feeding pipe. The auxiliary device comprises a bottom plate, supporting pipes fixed on the bottom plate and supporting pipe flanges fixed on the supporting pipes, wherein the bottom plate is a rectangular straight and rigid plate, and the length of the bottom plate is equal to that of the bearing oil feeding pipe; the supporting pipes are cylindrical steel pipes; the plurality of supporting pipes are vertically fixed on the bottom plate; the distance between every two supporting pipes corresponds to that between every two supporting pipes on the main bearing oil feeding pipe; supporting pipe flanges which is of the same type with flanges on the main bearing oil feeding pipe are arranged at the tops of the supporting pipes; and in the manufacturing method, a first tool in the auxiliary device adopts a rack manufacturing unit to weld the main bearing flanges, a second tool adopts a pipe piece manufacturing unit to manufacture a main bearing oil feeding principal pipe, and finally general assembly is carried out. By the auxiliary device and the manufacturing method, the production accuracy and the production efficiency of the bearing oil feeding pipe of the marine diesel engine are improved.

Description

technical field [0001] The invention relates to a marine diesel engine, in particular to an auxiliary profiling tool used in the manufacture of a bearing oil inlet pipe on a marine diesel engine and a manufacturing method for a main bearing oil inlet pipe. Background technique [0002] In the manufacturing process of large-scale engineering machinery and equipment, the bearing oil inlet pipe fittings often need to ensure the connection tightness and reliability of the connecting flanges for a long time. Therefore, how to prefabricate large bearing oil inlet pipe fittings has always been in front of technicians. problem. [0003] Marine low-speed diesel engines are the core equipment of large ships. During the operation of ships, they often need to work continuously for several days or even weeks. During the whole operation process, it is necessary to ensure that the bearings everywhere, especially the main bearing, are well lubricated and cooled, which requires smooth circu...

AI Technical Summary

Problems solved by technology

[0006] 1. The production cycle is long, and the tubes are transferred many times, which increases the transportation cost

Moreover, repeated transportation and lifting also increased the probability of accidents

[0007] 2. At least 1 crane worker, 1 electric welder, 2 plumbers and 1 fire watcher are required during the on-site school management process, which consumes a lot of manpower and time
